Export Oracle Database Schema

How to Export Oracle Database Schema

Using Oracle Database Cloud Schema Service

For cloud-managed schemas, utilize the Oracle Database Cloud Schema Service to export your database schema. Export directly to cloud storage or secure FTP, accessible for legacy customers who purchased the service before August 2017. Retrieve your Oracle Cloud Storage Container URL from the Infrastructure Console to proceed.

Utilizing the Export Wizard in SQL Developer

To export metadata, data, or both from SQL Developer, navigate through Tools > Database Export to launch the Export Wizard. This function is ideal for preparing dump files for Oracle databases or Oracle Autonomous Data Warehouse.

Exporting with Data Pump Export Utility

For a comprehensive export, including data and metadata, use the Data Pump Export utility. This creates a dump file set that can be imported using the Data Pump Import utility. These utilities allow for partial or network-based data and metadata transfers.

Legacy Methods with exp and imp Utilities

For transferring data objects, the exp command invokes the Export utility, which supports XMLType data. However, it does not support FLOAT and DOUBLE data types. Use the Data Pump Export utility for these types. Remember, the Import utility version must match or exceed that of the Export utility for successful data import.

SQL*Loader for External Data

SQL*Loader is used to load external data files into Oracle tables, facilitating data transfer between different database environments.
